There’s been a bit of chatter recently about the quality of beer. I had a chat with our Production Manager, Ed Jefferies, about the systems we have in place to make sure our beer is the best quality by the time it gets to our customers and consumers. It turns out that how we handle the beer from the point of brewing to getting to the glass is pretty bloody important. The buzz word that’s going around is ‘Cold Chain’; Ed gave me the lowdown.
What is Cold Chain?
Cold chain is when you keep your beers chilled for as long as you possibly can in the supply chain; Ideally from the brewery right to the pint in your hand.
What’s our process?
For kegs, when kegs are produced they go directly to cold storage. They then get delivered directly to the customer where they go straight into cold storage. For exports, our beers are sent in cold storage shipping containers and sent to a chilled storage facility before distribution to our customers. For distribution throughout New Zealand, the only time that kegs are out of cold storage is in transit. This ensures that our beer is as fresh as possible by the time it gets to our customers and the final beer drinker.
What happens if the beer is not chilled?
If beer is not chilled, it ages a lot faster which reduces the freshness of the beer. They say that chilling your beer, it stays fresher for three times longer. This applies more for hop forward beers like IPAs, as hop flavours do drop off as the beer ages. With stouts and darker beers, a bit of age can sometimes be a good thing. For example, The Observer, now with a bit of age has mellowed them out and rounded it’s flavour – Imperium is at its peak right now.
What’s your biggest worry?
When it comes to bottled beer, it’s a bit of a different story. After leaving the brewery, our beer does go straight to cold storage. Once we have sold them to our customers, we have no control over where it’s stored. It could be sitting in an ambient warehouse over summer for a month essentially cooking. That’s obviously beyond our control, so that’s why all of our products are kept chilled when it’s in our control. We try to brew the very best beer that we can, and also take care of it the best that we can. We’re committed to making sure our quality is the best it can be. At the end of the day, our consumers want to have a good beer experience and we want to do everything that we can to ensure this.
